Added exception loop in main file
Keep the exception handling totally minimal until good design
Next step in implementation of exception handlers
Finished implementing exception handling in the two outer most files,
enough for now...
Implemented exceptions in the advection, grid and fields initialization
Implemented exceptions in diffusion init
Implemented the exceptions for the pressure init
Timeloop also fixed and bug in pressure solved
Added the exceptions to the force file
Introduced the exceptions in the thermo init
Put exceptions in cross
Put exceptions in stats init
And exceptions in the buffer initialization
Implementend the excptions in the boundary init
Put the last class, the buffers into exceptions
Moved the boundary generation towards the init function, to ensure that
the initialization order in the model constructur is allowed to be
random
Reorganize the model constructor, the order requirements are gone now
Fixed the serial compilation with exceptions
No leaks on proper exit
Eliminate the allocated flag from fields and instead initialize the
pointers at 0
